Topic: 4D-HPT Hammer (Read 12121 times)

The Hammer Four Density (4D) Core consists of four individual components, top flare ring, top cap, mid body and lower cap. All four-core parts are of different densities. The 4D-core body is placed in an offset position in the relation to the centerline of the ball. This is the ball’s drive mechanism.

The Hammer HPT, for Hammer Particle Technology, is the latest development in “Active” cover materials. HPT is the production process where millions of tiny material particles are interspersed throughout the urethanes used in producing the ball’s cover. These material particles create the ball’s grab on the lane resulting in increased frictin, causing more hook than balls with today’s reactive or conventional urethane covers.

The HPT cover creates a high rate of ball friction. Friction, combined with ball momentum, initiates the hook action while keeping the ball’s energy “in check” for devastating pin carry. The 4D core compliments the HPT cover, giving the ball drive and revs. What are the results? It’s coast to coast hook, baby! “Turning the Corner” just took on a whole new meaning.

I have been a Faball fan for years but was a bit turned off with the Syntactive Sledgehammer. Now this ball on the other hand is an awesome piece of technology. I drilled the HPT like I had my High rev 3-D drilled...the max hook drilling but I knew the cover wouold be too much for the lanes so I did a 6 way sand and took the cover to a 800 grit finish. With this finish I get medium length (35 feet), a very hard roll and surprising backend. I don't have a ton of wrist so backend with a dull ball is not normal in my hands. One thing that did bother me though is that when my ball arrived it had the CG kicked right about 1.5" from the line connecting the pin and HOT spot...made for a wicked weight hole. My normal conditions BTW are fresh heads with 1 days worth of carrydown on wood lanes and this ball turned the corner hard. Great ball but be careful how you drill it if the guy has slow ball speed.

As an update to my previous post on the 4-D. AFter toying withthe cover and trying different things for about 3-4 weeks I gave up on the 4-D. For my slower ball speed and amount of turn the ball was just too much on our house shot even with a 1500 grit Squeeky CLean polish over a 1000 grit cross cut sand job. I ended up plugging it and selling to a local high school kid. For a guy with lots of ball speed and not a ton of hand, this ball is perfect but reverse the scenario and it gets ugly very quickly. I can't wait for the Spike HPT.....I love the cover but the weightblock of the 4-D was too much for me to handle. Keep at it Faball....or you could just bring back the Black Hamemr and we'd all be happy :-)

I recently got my 4-D and already love this ball. I don't have enough wrist to use reactive balls on heavy oil unless I would play up second arrow. This ball gives me more hook than I would of ever supspected for me. It allows me to swing the ball in heavy oil which give many avantages. I got it drilled for med. flare large smooth arc early roll. I have used once in travling league far and I couldn't believe how much drive this ball had, I'm so use to leaving flat tens and solid fives, I was amazed by the way the ball reacted in the back end. This ball is almost as good as my high Rev. I have seen my team mate throwing one and he also has the same success story I have. Even though I'm a little partial to faball products I would recomend this ball to everyone.

have been struggling in one amf house i bowl in. the lane machine is not stripping very well and the backends are soft to start with and they are running a pretty heavy flat pattern so carry down makes it worse. i have left more five pin and splits included five pins in this league than the whole time i have been bowling (15 years). last year my average in this house was 211 it is now at 189.

i got a 4d/hpt about 2 weeks ago and it performs very well on these conditions.

the weight is 15.13, with 1/2 ounce of top weight, 5/8 finger, and negative 3/8 side. basically the hot spot is under the ring finger, cg is on center line above midline of grip, pin 1.5 inches from pap, weight hole 3 inches beyond pin on line with pin and hot spot. this is very close to a basic axis drill....the drill gets it into a roll fairly early....the aggressive cover stock keeps if from deflecting too much through the pin deck. it does not very hard but pin carry is very good. have been struggling to shoot 570....last night shoot 227-227-202=656.

even though this is a very aggressive core/cover stock combination....can be drilled to be very predictable and still carry on heavy oil.
